Name and briefly describe the 5 activities which cells generally participate in as part of their normal function
Cell is the basic structural and functional unit of a body. cell
contains organelles which carry different functions. the functions
of the cells include providing structure and support to the body,
control growth, transport of nutrients, producing energy, metabolic
reactions, reproduction.
structure and support: a group of cells together make a tissue, a
group of tissues together make an organ, a group of organs make an
organism. that means cells provide the structural base of all
organisms.
Growth: in organisms, tissues grow by multiplication of cells.
cells break down into two daughter cells which are identical to it.
it happens in the name of mitosis and meiosis.
Transport: cells allow passage of nutrients and gases for various
chemical reactions happen in the cells. for example cells allow
exchange of oxygen and carbon dioxide for the process of
respiration.
Production of energy: for an organism to survive, it requires
energy. hence the energy is produced through various reactions in
the cell. for example process of photosynthesis in plants and
process of respiration in animals.
Reproduction: cells undergo reproduction for the survival of
species. the reproduction is carried out by mitosis(asexual
reproduction) and meiosis(sexual reproduction).
